This mustelid species ranges throughout the length of Alaska 

 Peninsula and Unimak Island, but we have no records farther 

 west. Wetmore reported that they were partial to salt water as 

 well as fresh, ''frequently swimming boldly out to the islands, 

 lying off the coast." 



In 1925, I learned that a local trapper had caught 10 otters at 

 Urilia Bay in the winter of 1924-25. 



Lutra canadensis kodiacensis 



Goldman (1935) distinguished the Kodiak otter from the main- 

 land form. The type is a skull from Uyak Bay, Kodiak Island, 

 collected by C. Hart Merriam in 1899. There are a number of 

 other skulls from the same island. Otters occur on both Kodiak 

 and Afognak Islands, and in 1936, we saw a number of otter 

 skins at Afognak Village.

The northern sea otter is described as being larger than the 

 southern sea otter of the California coast, E. I. nereis. I collected 

 a single specimen at Ogliuga Island on August 4, 1937. It was an 

 old male, weighing 80 pounds, and its measurements, in milli- 

 meters, were as follows: Total length, 1,390; length of tail 

 vertebrae, 315; and length of hind foot, 242.
